It does.
4 Rows out MIGHT let you use the flash on someone if they are at the edge of the stage. But i’m pretty sure the flash range on that is 8 or 9 feet. So that’s skeptical at best.
You could try finding an added flash to work on it, and that would allow for MUCH better shots.
Other than that, it’s going to be a battle of keeping steady and having your subject constantly moving in low light. w/o the flash, you might be SOL. that is unless you take the ISO real high, but then it’ll get grainy as shit.
Just experiment tonight when it’s dark and see how grainy they get.
